I agree with this, and think this is most likely the best way to  
handle this. I have noticed, for example, that there are several  
pedestrian areas which are completely surrounded by buildings. Trying  
to create connecting ways could result in ways that go through  
buildings or other impassible objects. Therefore, as you suggest, we  
can only rely on existing links to the squares.

This has the side-effect of making the coding much easier. ;-)

This is also the same way that routing with my patch will work  
(provided there are linking ways), so at least that is consistent.

Thanks for your comments. Cheers.
